The impact of yeast temperature pre-treatment on bioethanol from corn mash fermentation
Ho, Dac Hai Nam (2013) The impact of yeast temperature pre-treatment on bioethanol from corn mash fermentation. MRes thesis, University of Nottingham.
For commercial corn mash to ethanol production it is known that increasing temperature can maximize ethanol yield, although care must be taken to avoid causing heat shock resulting in the death of the yeast culture. Despite the potentially negative effects of high temperature, short sub-lethal stress has been reported to procure a benefit to yeast cells. However, the effect of such yeast pre-treatment on bioethanol fermentations has not previously been investigated.
